This amusing little comedy was based on the play by Ernest Denny. Anthony, Lord Crackenthorpe (Orral Humphrey), studies spiders, and he has asked Mrs. O'Mara (Lillian Leighton), the widow of a zoologist, to collaborate with him on a book about the creatures. Mrs. O'Mara and her impetuous daughter, Peggy (Marguerite Clark) move into the Crackenthorpe mansion, much to the chagrin of Anthony's mother, Lady Crackenthorpe (Maggie Fischer). Lady Crackenthorpe is concerned that her son, the heir to the Crackenthorpe estate, will fall in love with Peggy -- not realizing that he's already in love with Peggy's mother. To keep Peggy out of the picture, she encourages the younger son, Jimmy (Jack Mulhall), to keep her away from Anthony. Jimmy is more than happy to oblige. Peggy at first isn't all that interested, but then she finds out that her mother has refused Anthony's marriage proposal until her daughter weds. So Peggy leaves a note claiming that she has married Jimmy and sneaks into his home while he is gone. Lady Crackenthorpe is furious -- even more so when she discovers they aren't married and her son may possibly be caught in a scandal. As a result, Peggy decides, all of a sudden, that she does love Jimmy and they must marry right away.
